Enhanced geothermal system (EGS) is a primary method to develop geothermal resources
stored in hot dry rock (HDR), but it faces several key problems, such as unreasonable …

The finite element method is a powerful and general numerical method used to simulate
subsurface processes. In this paper, we take recent hydraulic fracturing propagation …

We analyse a problem of a hydraulic fracture driven by a non-Newtonian shear-thinning
fluid. Fluid viscosity is described by the four-parameter truncated power-law model. By …

This work is focused on the development of a dynamic criterion for the arching and bridging
of spherical particles in a 3D suspension flow through a channel with plane walls. Elasticity …

One of the assumptions of Linear Elastic Fracture Mechanics is that the crack faces are
traction-free or, at most, loaded by bounded tractions. The standard Irwin's crack closure …

This paper investigates the problem of a radial (or a penny-shaped) hydraulic fracture
propagating in a permeable reservoir. In particular, we consider the fluid exchange between …

We analyse the influence of fluid yield stress on the propagation of a radial (penny-shaped)
hydraulic fracture in a permeable reservoir. In particular, the Herschel–Bulkley rheological …

In this paper a problem of a hydraulic fracture driven by a non-Newtonian shear-thinning
fluid is analysed. For the PKN fracture geometry three different rheological models of fluid …

In this paper the problem of a plane strain hydraulic fracture propagating in an elasto-plastic
material is analyzed. A new stress redistribution model for the proximity of the fracture tip is …
